Summary

This study tests whether performing intrauterine insemination (IUI) at 42 hours after a hormone trigger shot leads to more live births than the standard 36-hour timing. About 692 women with infertility will be randomly assigned to one of the two timing groups. The goal is to see if a small delay helps eggs and sperm meet at a better moment for fertilization.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: intrauterine insemination (IUI) procedure
What this could lead to: If successful, this could show that delaying insemination by a few hours boosts pregnancy and live birth rates for people undergoing IUI.
What could go wrong: This is a timing adjustment, not a new treatment, so the impact may be modest. The trial is still recruiting, and results may not apply to all infertility cases.
